---------------------------
Here are some logs I added in solr code to print the BitSet, hope it will be
useful

related code:
if (info != null && ((req = info.getReq()) != null)) {
Map context = req.getContext();
logger.info("sets is {}", sets.length);
for (FixedBitSet set : sets) {
logger.info("set is {}", set);
}
logger.info("totalHits={}", totalHits);
context.put("export", sets);
